Abstract: The presence of echo presented with ultrasonic propagation in a finite metal rod, the sound ray theory is used to analyse the wave mode conversion of ultrasonic propagation in a finite rod and the impact on echo by it, and the conclusion is drawn that the intervals of the echoes are decided by the rod’s diameter and wave velocity. The process of ultrasonic propagation through a rod and the final ultrasonic echoes are analyzed by the FEM. In the practical application, based on the results of the FEM simulation for ultrasonic propagation in rods and the selectivity of the material and dimension, the characteristic echo and following echoes are identified at time domain, aiming to extract characteristic echo from the ultrasonic signal.
